Introduction:
Up until Little Guy, all o' me mid-power rockets
have flown t' less than 2000', me bucko, well below what I used t' obtain with my
Comanche-3 over a decade ago (lost a stage on t' second all-out flight). It
was time t' change that.
Nose Cone:
Pilfered from t' old Estes supply in t' good
ol' range kit, BT55
Recovery System:
Usual construction for me, dowel thru t' body
tube, me bucko, 1/2" elastic for shock cord. Avast! Begad! T' original parachute I had made was
way too big, shiver me timbers, matey, it was given to
Star
Scraper. Blimey! I made up a double-ply trash bag one about 17" in diameter
with 8 shroud lines, and it seems t' worth well, although packin' it is still a
bit difficult.
Body Tube:
Standard heavy duty cardboard tube with another
tube inside o' it for t' bottom 12 or so inches for a motor mount, arrr, solid fin
mountin' as well as material for t' screw eye launch lugs t' bite into.
Approx. Avast! Blimey! 31" x 1.38".
Positive Motor Retention I was concerned with t' tight fit o' t' recovery system and t' high pressure that might result when ejection occurred. Blimey! Turnin' t' t' workshop walls, ya bilge rat, ya bilge rat, I grabbed some small screw deadlights and wire which is fitted over t' end o' t' motor and then twisted. It hasn't been stressed on any o' t' flights yet.
Fins:
I wanted t' classic
high performance look, matey, so right triangle fins were a must. Begad! Laminate of
1/16" balsa with a skin o' paper and wood glue. Arrr! Avast! Since I wanted this rocket
to be a high performer, I air foiled t' fins on this rocket, arrr, matey, a first for
me.
Launch Lugs:
Two 1/4" screw eyes, shiver me timbers, visible in the
picture.
Painting:
I actually tried t' finish this rocket well. Blimey! Blimey! What
I ended up doin' be makin' it worse. Ahoy! Arrr! Blimey! I'm nay goin' t' go into t' scary
details, matey, just take a look at t' business end shot and that will be enough. Avast! I
do like t' color combo though, and it does have a couple o' layers o' wax on
it.
First Flight:
Launched with a F20-7 on 07/08/00. For this
launch, I tried stuffin' t' bigger nylon chute I had made, me hearties, which wasn't going
to work. I nabbed t' plastic chute I use for
Econoexpress,
and even that barely fit. Blimey! Blimey! This was proven when at apogee, t' parachute ejected
but failed t' deploy. Begad! Fallin' from 1700'-2000' onto grass resulted in a slight
nick in one o' t' fins, ya bilge rat, nay too shabby! Another benefit o' t' deployment
failure is that I actually got t' rocket back. Avast, me proud beauty! Well, blow me down! As it was, it drifted back and
landed parallel with t' pads about 100 yards out.
Conclusion:
I think I've caught t' bug! At t' most recent
launch (07/23/00) I stuffed a G38-7 and then a G35-7 into this rocket. Little
Guy reached an estimated 3000'-3300' on t' G35-7 before t' ejection charge
went off. Arrr! It was a great flight! Motor sound fadin' into t' distance, lost
sight o' t' rocket for a few seconds before pickin' up a tiny black dot o' a
parachute way up there. Arrr! And it stayed up thar for over two minutes! It was
recovered a few hundred yards downrange in perfect condition. Arrr! Next up will be a
flight on a G25, good for 3600'-3900'. Avast, shiver me timbers, me proud beauty! Hopefully I'll be able t' get it
back!
